Power upgrade Hatsan AT- P1 5,5mm or cal .22

This is a upgrade in the powersetting for your Hatsan AT-P1 cal .22 By coincidence when I dismanteld this Hatsan to fix a other problem I found finaly a way to upgrade the factory power setting of 24 joule. After increasing the power, the AT-P1 consumes a lot more air and after one clip of 10 pellets you need to refill the air cilinder to get the best results. But you get 25% !!! more power out of your AT-P1.
